Seventeen boxes out on two trails that I monitor. I might put up another half dozen but I’m taking it a bit easier this year. The last two seasons I went way overboard and I suspect that more boxes won’t make a whole lot of difference. Placing too many boxes in a compressed area just didn’t produce the results I was hoping for. So instead of ten or twelve boxes (in pairs) at a local retired landfill I’ll limit it to four (two pairs). I’m interested to see if I attempted to crowd them to close. But the Tree Swallows definitely benefitted and I like them almost as well!
